小区开放对周边道路通行能力影响的定量分析

Researches on the Effects of Community Open to Traffic

针对小区开放对周边道路通行的影响,通过层次分析、仿真模拟、灰色关联等方法,分别构建了模糊综合评价、道路通行能力仿真、小区开放效果对比等模型,运用Loca Space Viewer、MATLAB等软件编程求解,研究得出所调研小区的评价结果为"良",所构造小区开放后道路通行能力提高率为37.84%、实际小区内部岔口数和外围出口数对开放后道路通行能力提高的影响程度大等结论。

Aiming at studying the effects of community openness to traffic, this paper takes methods of hierarchical analysis, simulation and grey correlation, and builds respectively models, such as fuzzy comprehensive evaluation, traffic capacity simulation and comparing the effect of community openness. By programming and calculating with LocaSpace Viewer and MATLAB, this paper draw a conclusion that the evaluation results of the researching community is ＂good＂ ; and opening the constructed area will improve the traffic capacity by 37.84% ; the numbers of internal forks and external exits have a great influence on the traffic capacity.
